Description

Miramap has developed their sensor into a sensor-suite that simultaneously collects high-accuracy underground soil-moisture data, ground-temperature data, digital-elevation data and high-resolution geometrically corrected photos. The suite consists of three sensors operating in the X-, C- and L-bands, a thermal-infrared camera, a lidar-scanner, and a digital photo camera, with all measurements location-marked with satellite positioning data. The picture is a composite of four datasets of the Danube dams at Nikolovo. The surface temperatures (top left) range between 25°C (dark blue, open water) and 50°C (white, dry and open fields), and correlate with the soil moisture data (bottom left) and lidar elevation data (bottom right). The optical image is presented top right.
